Abstract: A method for neutralization of the explosive content of mines and UXO by essentially completely consuming the explosive by combustion or decomposition before any explosion occurs. A charge of a compound that reacts with an extremely high heat-release rate is ignited on or near the casing of the device to be neutralized. The intense exothermic reaction generates high temperature combustion products that will disrupt the casing, thus leading to combustion or decomposition of the explosive. The holes melted in the mine casing enable ignition of a large area of the explosive charge and provide easy access for atmospheric air to support active burnout of the explosive. The apparatus comprises the compound that reacts with a high heat release rate, an ignition source, and a container for the assembly.

Abstract: A mine has a casing which encloses an explosive and a primary charge arranged in the center of the explosive near the bottom of the mine. A liner is connected over the explosive in order to delimit the explosive to generate the shape charge effect and a spacing member is arranged between the primary charge and the liner. The spacing member has an upper portion which defines an opening and a lower portion which faces the bottom of the mine. The lower portion of the spacing member is shaped substantially as a circumference of a frustrum of a cone, with a base facing towards the bottom of the mine. A triggering arrangement, having a fuze and a trigger is supported by a holder. The holder is located above the opening in the spacing member. The trigger extends from an upper side of the mine through the opening to act on the primary charge.

Abstract: A device for detecting a target and for detonating an explosive device includes a displaceable trigger wire attached to a movable or deformable trigger member, and a detection device for detecting movement or deformation of the trigger member. In the case of a movable trigger member, movement of the trigger wire causes movement of the trigger member, and the detection device generates a detonation signal in response to the movement to cause detonation of the explosive. In the case of a deformable trigger member, movement of the trigger wire causes deformation of the trigger member, and the detection device generates a detonation signal in response to the deformation that causes the explosive device to detonate. The detection device may be located in the explosive device, with the trigger wire extending out away from the explosive device. Alternately, the detection device may be located in a support member located apart from the explosive device.

Abstract: A safety-and-arming mechanism for explosive device having a body including a slider, at least one latch adapted to translate between first and second positions to block the slider and allow translation of the slider, respectively, and a biasing device for applying a constant force to the latch to urge the latch in the locking position. The biasing mechanism includes a blade disposed at an end of the latch, and the blade is adapted to provide the constant force due to pressing contact against an inside surface of a launcher tube for launching the explosive device. The blade is adapted to apply a substantially constant force to the latch despite changes in dimensional tolerances between the interior surface of the launcher tube and the explosive device.

Abstract: A trip wire type mine has a plurality of trip wires, each trip wire being wound on a reel and ejected through an opening in a body of the mine by means of an ejection system. The ejection system may include a cutting device to cut a lid in a plate forming a plane wall of the hollow body of the mine, a movable system to displace the cutting device, and a pyrotechnic charge to drive the movable system. A projectile is attached to one end of each trip wire, and the charge is also used to eject the plurality of projectiles through the opening, thereby deploying the trip wires and placing the mine in an operational state.

Abstract: A firing circuit for use in booby traps providing four different operatio modes. A capacitor stores energy which is discharged through an electrical detonator upon the activation of a silicon controlled rectifier. The silicon controlled rectifier is activated by transistor circuitry in the event of supply voltage depletion or the physical parting of a break-wire by a target. It is also activated by a delay-timer for timed self-destruction and by circuitry responsive to vibrations in the firing circuit generated by the target.

Abstract: A holder is disclosed for a mine fuze for an antitank mine, in which the mine fuze incorporates a booster charge, a detonator for initiating the booster charge, and a spring-biased firing pin for initiating firing of the detonator. The holder is dimensioned to fit into a mine-fuze location provided in the antitank mine, where the booster charge is in fuzed relationship with the explosive charge contained by the mine. The holder is also provided with connectors for initiators for initiating one or more explosive charges located in the ground, the booster charge being in fuzed relationship with the initiators when the holder and mine fuze are attached.

Abstract: An align at fire safe and arm and electrical power supply module 10 for an electronically fuzed land mine 12. The module 10 is removably mounted into the land mine 12. Reserve batteries 16 are contained in the module 10 and are energized when a safety pin 25 is removed during mine emplacement. A slider 30 is located in the module housing 14. When the slider 30 is in its safe position, the firing train 57 of the warhead 65 of the mine 12 is interrupted. When the slider 30 is driven into its armed position by a piston actuator 32 in response to an align signal being produced by the fuzing subsystem 87 of the mine 12, the firing train 57 is completed through a transfer lead 60 located in the slider 30. The firing train detonator 44 may then be functioned by an electrical firing signal produced by the fuzing subsystem which will event the warhead 65. Detonating the firing train detonator 44 before the slider 30 is driven into its armed position, self-neutralizes the mine 12.

Abstract: The present invention relates to a mine incorporating a pressure plate. Such a mine comprises, inter alia, a pressure plate, a pyrotechnic firing chain and an arming device. The pyrotechnic chain comprises a firing relay rotatably mobile in two substantially perpendicular directions to ensure alignment of the pyrotechnic chain by a double rotation of a support disc about a shaft and a mobile member about an axis. Maneuvering of an arming button ensures rotation of the mobile member; a clockwork timer device ensures rotation of the support disc. A further feature of the invention resides in the reversibility of arming, the opposite maneuver of the arming button ensuring that the mobile elements of the mine return to their intial position. In addition, an anti-blast device is incorporated in the pressure plate. The invention is applicable to anti-tank mines.
